To all whom it may concern Be it known that we, JosEPH J. WALSER and HARLAND FANKBONER, citizens of the United States, residing, respectively, at Ann Arbor, Mich, and in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in inking Mechanism, of'which the following is a specification.

The invention relates to printing press and more particularlyto the inking mechanism and cooperating parts, the invention being directed "and especially adapted in its chief aspects or features to inking mechanism fitted and adapted for fast rotary presses,suchas are'used for newspaper work and some magazine work.

Objects and advantages of the invention will be 'set forth in part hereinafter, and in part will be obvious herefrom, or may be learnedby practice with the invention; the same being'realized and attained through theinstrumentalities' and combination pointed out in the appended claims. The invention consists in the novelparts, arrangements, constructions, combinations and:.improvements herein shown and described. V i

ductor roller upon the "periphery of the ink drum. a Referring now'in detailto the embodiment illustrated by "way of example-in the accompanying drawings, a rotary printing couple-is represented having a form cylinder 1 with its shaft 2 running in bearings 3, and a cooperating impression cylinder t havlng its shaft 5 "running-in bearings 6. The web x-runs through between the'cy-linders in the usual manner and is printed upon by the plates upon the form cylinder 1.

In accordance -vv-ith' certain features of the invention, a ductor roller or like ink conveying device, or preferably a plurality thereof, are provided which travel along the periphery of the fountain roller, '01' of the ink drum, or of both, the quantity and duration of the conveyance or transfer of ink from one of said members to another being controlled by the extent 'of such travel is the ductor. roller along'the periphery of oneor the other-of said "members,'rather than by dwell or pause of the ductor roller in engagement. with the ink drum or fountain roller. f There is provided by the present invention an adaptation of a mechanism such as just described to. an inking system having a plurality of fountain rollers (whether operating in a single ink fountain or in a plurality of fountains) and-liaving a plurality of ink'drumsreceiving ink fromthe ductor rollers and conveying it to the same form or plate cylinder,"thereby constituting a multi-Supplyinking mechanism. I

In conjunction and cooperation with the foregoing, the. invention provides, but is not limitedtb, a reciprocating ductor roller,

and preferably toaplurality of such ductor rollers diametrallyedispjosecl in 5 one; :01 more pairs; The manner of ink conveyance or transfer hereinbefore described renders possible the employment "of a continuously iilQ-yiment' nd ep'qpe a oh aw i i in mea r a sing e f rm Pla y in e a plurality of such fountain rollers, al-

though it will be understood that in its ad -respe t th i event qn is ne J limited.

aiunet b ;wiih a i re 0f he ?iprcati e Quit r ller er telle s. a di i guishediir me ssly traveling -11.c-

. rotating fountain roller, and alsothef-em tor roller, the reciprocating ductor rollers are caused to travel in a path preferably circular and describing an are somewhat longer than that defined or limited by or between the common radius of the ductor roller support and ink drum and the common radius of the center of the ductor roller support and the fountain roller. This gives a possible longer path or extent of travelof the ductor roller along the periphery of the ink drum or the fountain roller, or both, and therefore gives a wider range and control of the ink supply.

In accordance with certain features of the invention, the ductor roller is resiliently impelled toward the ink drum and the fountain roller, thereby adapting and capacitating the ductor roller to effect and describe its travel along or over the periphery. of either or both of said other members, and in conjunction therewith settable or adjustable means are provided for moving or restraining the ductor roller, or rollers, against the action of their resiliently impelled means, to limit or vary and to govern the extent of the travel of the ductor roller along the periphery of the ink drum or fountain roller. Such .means further are provided in connection dependently of the adjustments or controls for the others, in case a plurality of ink drums or fountain rollers, or both, are employed as already described. This provides a means for controlling the quantity and condition of the ink conveyance and supply from'each fountain roller independently, and the conveyance and supply to each ink drum independently and at the same time controlling the same collectively as supplied to the plates upon the form cylinder 1.

More in detail as to certain features of the foregoing, a ductor roller reciprocates about a center in an are extending somewhat beyond a fountain roller and beyond an ink drum with both of which the ductor roller cooperates, the ductor roller being resiliently impelled outwardly radially to have the desired travel along the periphery of the ink drum, and of the fountain roller, or both.

Preferably such ductor rollers, operate in one or more diametrally disposed pairs,

' swinging about a common center by means of arms fixed to a common shaft, each ductor roller receivlng 1nk from its own fountain roller, and each conveying ink to its own ink drum, the ink drums contributing together to ink a common form cylinder or rather the plates thereon. Each ductor roller is provided with'its own settable governing (lGVlCGS, such as an ad ustable cam or"- cams for pressing back in aradial'direction the corresponding ductor roller,against its springs, more; or less to limit and control the extent of its travel along the periphery of the other member or members. The more the ductor roller is held back against its ripheral travel on the ink drum and the fountain' roller, and the less quantity of ink is transferred forward to the printingplates on the form cylinder.

In the embodied'form, these various features of the invention, while largely capable of separate and independent use, are associated together in a single mechanism and in cooperation one with another, and together with other features of the invention not heretofore mentioned, but which will'be later described and pointed out.

Referring to the details of the illustrated embodiment, a plurality of ink fountains are shown, one ink fountain 10 having a fountain roller '11 therein, and another ink fountain 12 having a fountain roller 13 therein. Each fountain roller is rotated in the proper direction and at desired speeid in any suitable manner, as by a usual type of gearing from the common machine drive (not shown.)

As embodied herein, and in accordance with certain features of the invention, as already pointed out, a plurality of ductor rollers are provided, shown herein as a pair of such rollers, 14, and 15, mounted respectively upon corresponding pairs of arms 16 and 17, which are fixed to a shaft or a corresponding pair of stub shafts, 18, journaled in the machine frame. Suitable means for rocking or reciprocating the shaft 18 are provided, and as embodied, there is fixed to the shaft an arm 19, driven bysuitable con nections from a shaft20. A's embodied the arm 19 is double, the two parts being spaced apart and having a transverse wrist pin 21 mounted in the end thereof.

Pivotally mounted on the wrist pin 21 is a connecting rod 22, which rod at its other end is pivotally connected to another connecting rod 23. The rod 23 at its opposite end 24 is pivotally connected to the strap 25 ofan eccentric 26, the eccentric'being mounted upon the shaft 20. There is thereby imparted a reciprocatory or'oscillatory movement in the pair of arms 16, 17 and their respective ductor rollers 14 and 15'are swung to and fro along an arc which is somewhat'longer than the distance between the respective common radii of the shaft 18 and the corresponding fountain roller and said shaft and the corresponding ink drum, to permit orv roller carrying arm, in compression between the corresponding journal box 31 and the inner end of the corresponding aperture 30.

In the embodied form for moving or predeterminately positioning the ductor rollers with respect to the ink drums, or the fountain roller, orboth (already referred to) the shafts 32 preferably project outwardly beyond their respective arms 16 and 17. Fixed to these projecting ends of the respective shafts 32, are cam rollers 35, which in the present embodiment cooperate-with the adj ustable cam, which works against the spring 33, to radially vary and determine the position of the ductor rollers to. govern the extent of their travel upon the respective peripheriesof the ink drum or fountain-roller, or both, to control the supply of ink to the printing plates on the press as already explained.

The embodied form of the cam control justreferr'edto comprisesan arcuate cam-36 located between the fountain roller 11 and its ink drum 37 or between the fountain roller 13 and its ink drum 38. The cam 36 is preferably multi-part, the partsrbeing independently circumferentially adjustable or positionable with respect to eachjother, so as to regulate the place of incidence of the ductor-roller both upon. the; fountain roller and upon the ink drum.

A detail of the embodied form of the cam is shown in- Fig. 3. The two circumferentially adjustable parts. 39 and 40 are pro-- vided with adjusting slots, one slot 41 being in the part 39, another slot 42 being the part 40, and two parts having common registeringslots 43where the parts 39 and 40 overlap. The various slots are provided with suitable clamping bolts 44, 45 and 46, threaded into the machine frame. The arms 16 and 17 and their respective ductor roller carrying slots 30 are so proportioned that when the respective springs 33 are permitted to press the journal or bearing boxes 31 to the outer ends of the slots 30, the path of the outer part of the ductor' roller would describe the arc or circle indicated by the line 47 in.- Fig. 5, andthe extreme outer part of the roller 35 would, describe the path indicated bythe line 48 in Fig. 5. Thus the .ductor roller will travel over the periphery of the, other drum or roller, the springs 33 compressing and then expanding to permit this motion. The cam rollers 35 are so pro? portioned that as they roll: along the ame they will be brought to the speed of the ink drum or of the-ductor roller, respectively.

Due to this position of the path. of. the ductor rollers and to their resilient impulsion radially outwardly by the springs 33, they are capacitated to tra-vel'or roll along the periphery of the ink drum 38, and the fountain roller 13, and of the ink drum 47 and the fountain roller 11, as the case may be. The circumferential and relatively independent adjustment of the parts 39 and 40 of the cam 36 govern or control the extent of such peripheral travel, as desired,

with either the ink drum or fountain roller, independently of the other; The provision of such means at each side obviously makes the adjustment or control of each side or part of the mechanism independent of the other. 1

By the circumferential adjustmentv of the: part 40 of cam 36, the point of rise or departure of the ductor roller from the fountain roller can be exactly governed, thereby giving a nice and accurate control of the quantity of ink taken by the ductor roller: from the fountain roller. By the circumferential adjustment of the part; 39 of cam 36 to or from the ink. drum, the point in the travel of the ductor roller is determined at which it will come into contact withthe periphery of the ink drum, and thereby an equally nice and accurate control isobtained of the delivery of the ink from the ductor roller to the ink drum. 3'

The remaining parts of the-inking mech anism, shown herein more or less conventionally, comprise as so shown transferring rollers 50 and 51, form roller 52, ink, drum 53, form roller 54'andv a distributing roller 55 cooperating with formroller 52, v

The ink drums 37, 38 and 53 and the roller 55,,in the preferred form, are all vibrated, and the ink drums 37. 38 and. 53 are likewise positively driven, in the usual manner while theroller 55 is frictionally driven from form roller 52. In the embodied form of vibrating means, there is fixed on the shaft'20 an eccentric'56, the strap 57 thereof being connected toa rod 58. The rod 58 is pivotally connected to an arm 59, whichj arm is fixed to. a-shaft the machine frame. I

'Fixed to the shaft 60 is an arm 62, provided with a roller 63, which roller runs in an annularly grooved collar 64 formed upon the shaft 65 of ink drum 38. The ink drum 5 6O journaled in. afbracket 61 mounted upon I is. positively rotated from the other end of &

with which meshes a geared sector 75, fixed to a shaft 76, which shaft is journaled in a bracket 77 carried on the machine frame. From shaft 76 an arm 78 extends downwardly and is provided with a roller 79, said roller working in an annularly grooved collar 80 on the shaft 81 of the ink drum 37. The ink drum 37 is likewise positively driven from the other end of its shaft in a well-known manner. From the shaft 76 an arm 84% extends upwardly and carries a roller 85, said roller working in an annularly grooved collar 86 on the shaft 87 of theink drum 53, which ink drum, like the others, is driven from the other end of its shaft in any known or approved manner.

The general operation of the mechanism will be clear from what has already been said. It willbe noted in Fig. 5 that the circular path to, or toward which the ductor roller is resiliently impelled is indicated as 47, this being the path of the outer point on the periphery of the ductor roller. The inter-sections of are 47 with the periphery of ink drum 38 will measure the maximum travel of the ductor roller along the periphery of the ink drum. This travel involves a concurrent backward radial movement of the ductor roller against its resilient mounting, in this case the spring 33. The actual path of the ductor roller from the point of incidence, however, is not the arc 47, but the arc of the periphery of the ink drum 38 which is included in the arc 47, except that this is modified by the position of the cam'36.

In Figsfi and 7 are shown somewhat diagrammatically the path of travel of the center of the ductor roller 14. Either position of the ductor roller may be taken as the point at which it leaves cam 39 and comes in contact with ink drum 37 or 38, but from such point of incidence the center of the ductor roller travels along the arc c, which is concentric with the ink drum, the

ductor roller thus rolling along the periphcry of the ink drum. Due to the rotation or oscillation of the arm carrying the ductor roller it reaches a point where it again would follow the are 6. 7 This position, which is predeterminately variable, is the in ter-section of the arcs b and 0 in Figs. 6 and 7, and the position a in Fig. 1. It will be understood that where the ductor roller oscillates, as in the present embodiment, that this is preferably the approximate point of its reversal of motion.

The action at the fountain roller will be clear from the foregoing without further description.
